CryBrazil virus Removal Guide
What is CryBrazil ransomware?
CryBrazil ransomware – malicious crypto-virus targeting Portuguese and Brazilian PC users
CryBrazil ransomware is a dangerous crypto-virus that was generated with the help of Hidden Tear open-source project which helps hacker-wannabes to create their own ransomware. At the moment, this money-extorting virus is used to swindle the money from Brazilian and Portuguese users,[1] but there is no guarantee that this malware won't start spreading all around the world. Riansomware[2] is using the .crybrazil file extension to mark encrypted files and make them unusable. Additionally, Cry Brazil drops ranso4.jpg or SUA_CHAVE.html ransom note that is filled with joker image and a step-by-step guide needed for unlocking encrypted files. Besides, the website users are redirected to by these ransom notes is also promoting the fake Adobe Flash Player, such as Flash Player Update! or Flash Player is out of date scam.

| Ransom note | ranso4.jpg; SUA_CHAVE.html |
| Target countries | Brazil and Portugal |
| Decryption | Not available |
| ELIMINATION | FortectIntego is the best tool for virus removal |
The ransom message is provided in Portuguese language only. While it is not very informative, it provides an email address that should be used to reach hackers hiding behind this version of HiddenTear. However, the email address which is given in the ransom note of the Cry Brazil virus is supposed to help victims understand the whole situation. The whole ransom note reads:
Ele que é o palhaço, mas sou eu quem põe fogo no circo.
ATENÇÃO CRIANÇAS!
Todos os seus arquivos foram criptografados, para recuperá-los de volta entre em contato: LOSALPHAGROUP@PROTONMAIL.COM
Nevertheless, we do not recommend using this or any other Protonmail.com-related email to contact strangers and malicious actors. Previously, ransomware developers have been relying on these email addresses:
- Unlckr@protonmail.com;
- Garryweber@protonmail.ch;
- Recuperadados@protonmail.com;
- Recoverhelp@protonmail.ch;
- etc.
Once you notice malicious extensions next to your files, you should remove CryBrazil ransomware and any files related to this malware. Do not pay the ransom, no matter how big or small it is because, by doing so, you do not get any guarantee that hackers will send you the needed key for files' decryption. In most of the cases, they just leave their victims with nothing.[3]
Since CryBrazil can change Windows registry and drop malicious files onto the system, we highly recommend using professional software for its removal. Cybersecurity specialists from Avirus.hu[4] and other websites note that the easiest way to detect the virus is to use automatic removal software. The best solution for this type of virus is FortectIntego.
However, you should also note that CryBrazil removal should be initiated before you start restoring your files. If you don't have backups of your encrypted data, you can rely on several methods that we give at the end of this post. Official decryptor is still unavailable for this ransomware.
The threat spreads thru spam
The main way to put yourself at high-risk of getting ransomware infection is opening insecure emails without double checking them first.[5] Malware, including ransomware viruses and similar threats, can get into your computer without expecting, so you should always look at the sender's email address and the body of the message before downloading the attachment on clicking on the link that could also be included. If you see something suspicious (typo or grammar mistakes, deals that seem too good to be true, and similar information), you should either contact the sender or simply delete the email.
Another way to get infected is unwise browsing on the Internet. Keep in mind the web is full of fake notifications and deals that are typically used to trick users into downloading “missing” updates and similar software. In reality, these eye-catching notifications should be ignored, especially if you run into them while browsing thru adult-related, gaming, and similar websites. Always think twice before clicking on suspicious ads online.
Remove CryBrazil ransomware to encrypt your files
To remove CryBrazil virus from the system, you should act immediately after noticing any traces related to this ransomware. Otherwise, it may start yet another encryption session. If you can see malicious extensions next to your files, use FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes for a full elimination of the virus. Any files related to this virus might cause additional damage after the cleaning process, so we highly recommend using anti-malware software and updating it before a scan.
Once you finish CryBrazil removal, go straight to file recovery procedure. There are several ways to do that, but the most reliable one is related to backups. Third party tools and other methods that we recommend below cannot be considered as effective as backups. However, you have nothing to lose when you are dealing with such consequences of the virus. If CryBrazil ransomware is trying to disable your anti-virus, use steps given below to disable malware before a scan.
To prevent such data loss in the future, you should backup every file that you find important for you. Ransomware is a nasty piece of software which continues spreading around the globe and can infect every system which is poorly protected.

How to prevent from getting ransomware
Access your website securely from any location
When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.
If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
